beam

Returns a beam.

Description

A beam

[ ]

Usage

1. Example

   a = FoscStaff(FoscLeafMaker().(#[60,62,64,65], [1/8]));
   set(a).autoBeaming = false;
   a[0..1].beam;
   a[2..3].beam;
   a.show;

   

2. Example

   a = FoscStaff(FoscLeafMaker().((60..75), [1/32]));
   set(a).autoBeaming = false;
   a[0..].beam(durations: 1/8 ! 4, spanBeamCount: 1);
   a.show;

   prFormatCodeString interpret initial failed: a DoesNotUnderstandError
   
   a = FoscStaff(FoscLeafMaker().((60..75), [1/32]));
   set(a).autoBeaming = false;
   a[0..].beam(durations: 1/8 ! 4, spanBeamCount: 1);
   

3. Partition selection by sizes and beam each new selection.

   a = FoscStaff(FoscLeafMaker().((60..75), [1/32]));
   set(a).autoBeaming = false;
   a[0..].partitionBySizes(#[3,4,6,3]).do { |sel| sel.beam };
   a.show;

   

4. Beams can be tweaked.

   a = FoscStaff(FoscLeafMaker().((60..75), [1/32]));
   set(a).autoBeaming = false;
   a[0..].partitionBySizes(#[3,4,6,3]).do { |selection|
       b = FoscStartBeam(direction: 'up', tweaks:#['positions', [6,6], 'color', 'grey']);
       selection.beam(startBeam: b);
   };
   a.show;

   

5. Specify spanning beams using durations and spanBeamCount.

   x = FoscLeafMaker().((60..83), [1/16]);
   d = [[1/4, 1/8],[1/8, 1/4],[1/4, 1/8],[1/8, 1/4]];
   m = x.partitionBySizes(#[6,6,6,6]);
   m.do { |sel, i| sel.beam(durations: d[i], spanBeamCount: 1) };
   x.show;

   d = [[1/4, 1/8],[1/8, 1/4],[1/4, 1/8],[1/8, 1/4]];
   m = x.partitionBySizes(#[6,6,6,6]);
   m.do { |sel, i| sel.beam(durations: d[i], spanBeamCount: 1) };
